LLDP-MED Network Policies TLV
A network policy in the context of LLDP-MED is a device’s VLAN configuration and associated Layer 2
and Layer 3 configurations, specifically:
• VLAN ID
• VLAN tagged or untagged status
• Layer 2 priority
• DSCP value
The application type is a represented by an integer (the Type integer in Table 26-6), which indicates a
device function for which a unique network policy is defined. An individual LLDP-MED Network Policy
TLV is generated for each application type that you specify with the FTOS CLI (Advertising TLVs on
page 592).
3 Endpoint Class 3
4 Network Connectivity
5-255 Reserved
Note: With regard to Table 26-6, signaling is a series of control packets that are exchanged between an
endpoint device and a network connectivity device to establish and maintain a connection. These signal
packets might require a different network policy than the media packets for which a connection is made. In
this case, configure the signaling application.
